About the company

Vertiv builds power and cooling equipment that keeps data centers, communication networks, and industrial facilities running through outages and heavy computing loads. Its Liebert cooling systems manage the heat generated by servers, while its power products protect equipment and distribute electricity. The company sells equipment directly and through distributors, then earns additional revenue from installation, maintenance, spare parts, and services throughout the equipment life cycle. Its portfolio also includes racks and software for monitoring and managing IT equipment. Vertiv became a standalone company in 2016 and is headquartered in Westerville, Ohio.

What critics are saying

  • Large deployments strain delivery: Vertiv reported supply-chain congestion and project timing shifts in July 2026.
  • Booked demand carries cancellation risk: Vertiv's $15 billion December 2025 backlog allows customers to defer or reduce commitments.
  • Job security faces cost targets: Vertiv's ongoing restructuring program includes workforce reductions across all segments.

What makes Vertiv unique

  • Cooling expertise predates the AI boom: Liebert pioneered precision computer room air conditioning in 1965.
  • Modular sites support varied power standards: Vertiv SmartMod integrates factory-tested enclosures with 12V, 48V, or 400V DC.

Vertiv shares fall 39% ahead of Oct 28 earnings as AI delivery faces test

Vertiv (NYSE: VRT) reports third-quarter results on October 28, with investors looking for proof that delayed AI projects are now shipping. Shares have fallen 39% from their first-quarter report price of $319.09 to $194.31, about 29x 2026 consensus EPS. The stock dropped 17.26% after second-quarter results, despite revenue up 24.1% to $3.27 billion and adjusted EPS up 60% to $1.52. Organic growth slowed to 18%, which management blamed on supply chain congestion and project timing. Guidance for the third quarter calls for about 35% organic growth, a 24.5% adjusted operating margin, and $3.75 billion in revenue. Options traders look cautious, with a put/call ratio of 2.54. On October 21, Vertiv said its NVIDIA DSX approach targets up to 30% more cumulative AI token output in the first 12 months.

Vertiv shares fall 8.65% to $193.80 despite model showing 30% more AI output

Vertiv shares fell 8.65% to $193.80 at about 11:46 ET on Thursday, even as the data-centre power and cooling supplier said a new deployment model could speed up AI projects. Using NVIDIA DSX, Vertiv modelled up to 30% more cumulative AI token output in a project's first year. Its scenario cuts design and validation from 30 days to three, and halves infrastructure deployment from 90 days to 45. That yields 317 productive days instead of 245. The gains are modelled, and actual results depend on execution. Polar Data Centers is applying the factory-built approach to the first 41-megawatt phase of its Herya campus in Norway. Vertiv's second-quarter adjusted operating margin was 22.6%, up 410 basis points year over year.

Dassault Systèmes and Vertiv partner to cut AI factory deployment time by up to 50%

Dassault Systèmes and Vertiv Holdings Co. announced a collaboration to let AI factory infrastructure be configured, simulated and validated before construction begins. The companies aim to cut field complexity and speed up deployment of NVIDIA DSX AI factories. Vertiv's SimReady power and cooling designs will run on Dassault Systèmes' 3DEXPERIENCE platform as configurable virtual twins. The work builds on Vertiv's SmartRun twin and extends to solutions such as Vertiv OneCore. The companies target up to 10x faster progress from requirements to a validated design, and up to 50% less deployment time. In Vertiv's model, capacity comes online about 10 weeks sooner, yielding up to 30% more token output within 12 months. The gain comes only from earlier readiness, not a measured customer result. The companies are showing the approach at NVIDIA GTC Berlin, October 20-22.

Vertiv Holdings Co. and NVIDIA introduce AI Factory approach using NVIDIA DSX and Vertiv factory-built infrastructure.

Vertiv Holdings Co. and NVIDIA introduce AI Factory approach using NVIDIA DSX and Vertiv factory-built infrastructure. Published on 10/21/2026 at 08:50 am EDT S&P Capital IQ Vertiv Holdings Co. and NVIDIA introduced an AI factory approach that combines rapid configuration and virtual validation of pre-engineered reference architectures with factory-built deployment. The approach is designed to move AI factories from project kickoff to productive capacity faster and, under defined assumptions, generate up to 30% more cumulative token output within the first 12 months with the same installed capacity. The Vertiv and NVIDIA approach starts instead with pre-engineered AI factory reference architectures that can be rapidly configured to customer and site requirements, virtually validated before deployment, then translated into factory-built infrastructure. Teams can start with pre-engineered AI factory reference designs and rapidly configure them for specific compute, power, cooling and facility requirements in a shared virtual environment. The approach combines the NVIDIA Vera Rubin DSX AI Factory reference design and NVIDIA Omniverse DSX Blueprint, with Vertiv SimReady power and cooling assets, integrated with Dassault Systèmes' 3DEXPERIENCE agentic platform. Rather than developing an integrated infrastructure design from scratch, teams can configure and virtually validate proven reference designs against project requirements, interfaces and constraints. In the modeled scenario, this reduces the time from requirements to a configured and validated AI factory solution from approximately 30 days to three days, a 10x improvement. Vertiv is also contributing SimReady OpenUSD assets of its power and cooling equipment to SimReady Central Library on Hugging Face. The library helps engineering teams discover and reuse validated equipment assets in AI factory digital twins, reducing asset preparation and helping teams evaluate infrastructure options during design. Once the AI factory configuration is validated, Vertiv prefabricated solutions shift more assembly, integration and testing into the factory before equipment reaches the site. These solutions include Vertiv? OneCore, a hybrid-built data center solution that integrates critical power, thermal management and supporting infrastructure, and Vertiv? SmartRun, a prefabricated overhead infrastructure system for high-density power distribution, liquid cooling, networking and containment. By moving more infrastructure work off-site, teams can reduce field complexity and on-site integration requirements. In the modeled scenario, the factory-built approach reduces the infrastructure deployment period from approximately 90 days to 45 days, a reduction of up to 50%. Combined with the faster configuration and validation enabled by pre-engineered reference designs, the modeled approach reduces these stages from approximately 120 days to 48 days. That can make productive AI capacity available about 10 weeks sooner, generating up to 30% more cumulative token output within 12 months of project kickoff with the same installed capacity.

Vertiv and NVIDIA target 30% more AI token output in year one; Polar deploys 41MW Norway site

Vertiv and NVIDIA have introduced an AI factory approach that pairs pre-engineered reference designs with factory-built infrastructure. Announced at NVIDIA GTC Berlin, it aims to bring AI capacity online sooner. In modelled scenarios, it yields up to 30% more cumulative token output in the first 12 months at the same installed capacity. The modelled approach cuts configuration and validation from about 30 days to three, and deployment from about 90 days to 45. Together, that trims these stages from roughly 120 days to 48, making capacity available about 10 weeks sooner. Polar Data Centers is using the factory-built model for the first 41 MW phase of its AI data center at Herøya, Norway, which is scalable to 100 MW.
